Design of steel and composite structures for robustness

摘要

The paper briefly reports on investigations concerning the robustness of steel and compositernstructures. When applying the alternate load path method for redistributing the loads resultingrnfrom a column loss especially the detailed consideration of the behaviour of beam‐to‐columnrnjoints is important. A crucial aspect is the investigation of the available rotation capacity of thernjoints as well as the required rotation capacity of the joints. Finally a method is presented that canrnbe used in order to verify the rotation capacity for permanent load situation as well as for accidentalrnload situations.
